x^2= 8/9

解

x^{2} = \frac{8}{9}

解

x = \frac{2 2}{3}, x = - \frac{2 2}{3}

+1

十進法表記

x = 0.94280 \dots, x = - 0.94280 \dots

解答ステップ

x^{2} = \frac{8}{9}

x^{2} = f (a)

の場合, 解は

x = f (a), - f (a)

x = \frac{8}{9}, x = - \frac{8}{9}

\frac{8}{9} = \frac{2 2}{3}

- \frac{8}{9} = - \frac{2 2}{3}

x = \frac{2 2}{3}, x = - \frac{2 2}{3}
